Neck turning tools?

Which one is the best to use? And is it worth it for accuracy on a hunting long range gun? I use Nosler brass for my 7mm rem mag and for my 7mm Dakota I use Norma brass. I have never turned a neck but if will increase my accuracy I will by one, so I need some opinions guys. I like to get as much accuracy out of my guns as I can squeeze.
Thanks

Give Sinclair International (800-717-8211) a call and order their NT-1000 or NT-3000 for turning necks. I have used their NT-1000 for awhile and find it easy to use. I use it with a cordless drill set-up.

If you don't have a "tight neck" chamber, you will most likely not see any improved accuracy by turning your necks.

I disagree. Your brass doesn't have any idea if it's being fired in a tight neck chamber or not. All it does is blow out until it contacts the neck of the chamber and then springs back some. So this idea that you only turn your necks if your chamber is tight just to make it fit in the gun is like trying to take an oral temperature by sticking the thermometer in the rectum. In other words, people didn't start neck turning to make brass fit, they started neck turning to make the brass UNIFORM in thickness. Of which the result is you make your brass thinner and therefore (for less work hardening) the neck diameter needed to be reduced to control the blow out of the brass and minimize the springback.

Why make the neck wall thickness uniform? Striaght bullet release. Pure and simple. It also makes the loaded round more concentric because the sizing die isn't squishing in a fat side of the neck anymore. These things are both benefits of neck turning regardless of how much clearance you have between the loaded round and the chamber walls.

Now, if you have a great barrel with an optimum oscillation, it may override the fact that the brass hasn't been turned, but turning would still make it shoot even better. What percent? 1%, 10%, 90%. Who knows. Some barrels won't show as much of an improvement as some others but the fact remains that wringing the best accuracy from any rifle requires all the variables be eliminated. And uneven brass is a variable.

your using really good brass and what I found using norma and nosler is they have more uniform than win, fed, and horn brass. i am in the same boat. i am researching neck turning tools myself. sinclair looks like they have what I need.

Thank you for the information this is very informative, one of my guns I'm building now will have a stiller predator action so I know the tolerences will be slightly tighter so I will neck turn for that gun, and my other gun I will try some loads that shoot very well and turn the necks to see if it helps my groups a bit!

K&M Services and Sinclair are both considered top of the line manufacturers of outside neck turning tools. I use the K&M Services neck turner and have no complaints. Never used a Sinclair but the function of both brands of tools is pretty much identical.
